Abstract:
In-progress call transfer between a wireless telephone and a wired telephone is effected using a short-range wireless communication link between the devices. Each of the devices are provisioned to include a short-range radio or infrared transceiver so that the devices can communicate with each other over the short-range wireless communication link, preferably using a given short-range wireless protocol. When the wireless telephone's battery is almost exhausted, or for any other reason that the user may desire, the wireless telephone requests the wired telephone's phone number by communicating with the wired telephone over the short-range wireless communication link. Upon receipt of the wired telephone's phone number, the wireless telephone issues a call transfer request to a cellular base station, passing the wired telephone's phone number. The base station and the network then re-route the call to the wired telephone.
Abstract:
A wireless patient monitor is adapted to communicate with any one of plural medical telemetry networks, each having one or more central stations, where each network is configured to communicate via wireless communications using one of multiple different communications settings. The monitor includes one or more sensor inputs for receiving vital signs data from a patient, a wireless transceiver; and a controller coupled to receive the vital signs data via the one or more sensor inputs and to communicate with a network via the transceiver. The monitor also includes a display device and is controllable by the controller to automatically display a notification to a user of the monitor upon establishing communications with the at least one central station. There is also a method of monitoring a patient and a wireless medical telemetry system.
Abstract:
The invention relates to a method for supporting the quality of service (QoS) in packet data transmission between a wireless terminal (MT), having data communication with a radio access network, and a data network (LN), in which method data transmission between the terminal (MT) and the radio access network (2) is controlled by at least one mobile IP router (5, 5', 5''). Further, in the method data is transmitted in radio flows between the wireless terminal (MT) and the mobile IP router (5, 5', 5''). In the method, a flow label is defined for at least one radio flow and the desired quality of service is defined for the radio flow.
Abstract:
Known is a communication system such as a cellular mobile radio system comprising a cellar network and a plurality of terminals. The system can have multi-rate codecs. These days, apart from a basic service such as full duplex or semi-duplex speech communication, such systems offer services as voice mail, voice messaging, or the like. In order to make more efficient use of system resources, in particular radio resources, for one-way voice communication, it is proposed to set the multi-rate codecs at a lower bit rate than for a two-way voice communication. Establishing whether a communication is a one-way voice communication can either be done a priori or dynamically. Use is made of the insight that a longer terminal-to-terminal delay can be applied for such a one-way communication because no echo cancelling has to be done in that case. For full flexibility, an asymmetric encoding and decoding can be applied.
Abstract:
In a re-routing procedure according to the invention, in-stead of establishing a new connection, the context information is modified only in those network elements which the change in routing concerns. The necessary context information about the connection is loaded to the new network element. Additionally, the other network elements participating the connection are informed of the change of the network element.
Abstract:
The invention relates to packet-switched transmission of calls and particularly to packet-switched transmission of calls on circuits between a telecommunication network and base stations from the base stations toward the network. The reduce the maximum delays and the variation in the transmission times of call packets, control packets that contain signalling information on the data transmission network are separated from the call packets in the network node in the present method, information on the arrival rate of the call packets is maintained, the duration of the control packet that is to be sent next is calculated (22), the interval to the reception of the next call packet is defined (23), the duration is compared (24) with the interval, and if the duration is shorter than or equal to the interval, the control packet is sent (25), and if the duration is longer than the interval, the control packet is put (27) in a transmission queue, it is waited until said call packet has been received, and the packet is then forwarded substantially immediately.
Abstract:
The invention relates to method for calling by a terminal, like a card controlled mobile station, of a mobile communication system, in which method the terminal is controlled by a SIM-card and the subscriber is identified from data of the said SIM-card. Characteristic for the invention is that by attaching a mobile station to special teleterminal adapter a local subscriber status is given to the mobile terminal.
Abstract:
Certain aspects of the present disclosure provide methods and apparatus for implementing extended signaling in wireless communications. An example method generally includes communicating with a second apparatus using one or more communications channels defined by a radio access technology (RAT) standard, and communicating with the second apparatus via extended signaling not defined by the RAT standard.
Abstract:
A first mobile station operating on a first network according to a first network protocol receives a proxy request for access to a network resource, by from a second mobile station operating on a second network according to a second network protocol. The proxy request is received according to a third network protocol. The first mobile station determines a priority of the proxy request; accepts or denies the proxy request based on the determined priority of the proxy request; allocates resources to the proxy request, if the proxy request is accepted; and serves as a proxy mobile station for the second mobile station to access the network resource.
Abstract:
Certain aspects of the present disclosure relate to techniques for managing radio link failure recovery for a user equipment (UE) connected to a WWAN and a WLAN. The techniques may include establishing communication with a first radio access technology (RAT) and a second RAT. At least one data flow may be transmitted over each of the first RAT and the second RAT. Determinations may be made as to whether to maintain the at least one data flow over the second RAT when a radio link failure (RLF) is detected at the UE and/or whether to resume the at least one data flow over the second RAT upon RLF recovery. The determinations may be made at the UE, at a network entity in communication with the UE, or some combination thereof.
